Question

我有一个遗留的解决方案，我一直在逐步升级，现在想要使用PackageReference而不是packages.config将.csproj和.vbproj文件升级到新的2017格式。

整体解决方案有大约60多个项目，因此手动迁移将非常痛苦。我一直在寻找一个实用程序来自动化该过程而没有成功。有没有人知道这样做的任何脚本？

我已尝试使用NuGet PackageReference Upgrader，但ID不起作用。我在输出窗口中出现以下错误

使用PackageReference转换为VS 2017 .csproj格式

我创建了一个带packages.config的简单示例，我可以通过NuGet PackageReference Upgrader工具将其迁移到PackageReference。根据错误日志很难找出导致错误的原因。

如果您有兴趣，可以通过Q & A与该扩展程序的所有者联系。

要完成将Packages.config迁移到PackageReference，您可以下载 Visual Studio版本15.7预览版3 ，该版本支持从packages.config管理格式迁移项目到PackageReference格式。查看Visual Studio博客：Visual Studio 2017 version 15.7 Preview 3以获取更多详细信息。
